Assuming the data you want to work on are in the tables, you could use a macro like:
Code:
Sub Demo()
Application.ScreenUpdating = False
Dim Tbl As Table, r As Long
For Each Tbl In ActiveDocument.Tables
With Tbl
.Shading.BackgroundPatternColorIndex = wdGray25
For r = .Rows.Count To 2 Step -1
If Split(.Cell(r, 1).Range.Text)(0) = "rejected" Then .Rows(r).Delete
Next
End With
Next
Application.ScreenUpdating = True
End Sub
